16th International Workshop on the Implementation of Logics
https://eprover.org/EVENTS/IWIL-2026.html

CALL FOR PAPERS: deadline August 10th, 2026.

The 15th International Workshop on the Implementation of Logics will be held on 25th October 2026, in conjunction with the 26th International Conference on Logic for Programming, Artificial Intelligence, and Reasoning, on Spetses, Greece.

We are looking for contributions describing implementation techniques for and implementations of automated reasoning programs, theorem provers for various logics, logic programming systems, and related technologies. Topics of interest include, but are not limited to:

- Propositional logic and decision procedures, including SMT
- First-order and higher order logics
- Non-classical logics, including modal, temporal, description, non-monotonic reasoning
- Formal foundations for efficient implementation of logics
- Data structures and algorithms for the efficient representation and processing of logical concepts
- Proof/model search organization and heuristics for logical reasoning systems
- Data analysis and machine learning approaches to search control
- Techniques for proof/model search visualization and analysis
- Practical constraint handling
- Reasoning with ontologies and other large theories
- Implementation of efficient theorem provers and model finders for different logics
- System descriptions of logical reasoning systems
- Issues of reliability, witness generation, and witness verification
- Evaluation and benchmarking of provers and other logic-based systems
- I/O standards and communication between reasoning systems

We are particularly interested in contributions that help the community understand how to build useful and powerful reasoning systems, and how to apply them in practice.

Researchers interested in participating are invited to submit a position statement (2 pages), a short paper (up to 5 pages), or a full paper (up to 15 pages) via the EasyChair page for IWIL2026: https://easychair.org/conferences/?conf=iwil2026

Submissions will be refereed by the program committee, which will select a balanced program of high-quality contributions.

Submissions should be in standard-conforming PDF. Final versions will be required to be submitted in LaTeX using the easychair.cls class file. The proceedings will be published as a volume of Kalpa Publications in Computing.

Important Dates:

- submission of papers/abstracts: August 10th, 2026
- notification of acceptance: September 3rd, 2026
- camera-ready versions due: September 17th, 2026
- workshop: October 25th, 2026
